About these units
US Cup (cup)
One sixteenth of a US gallon, 236.588 mL (8 US fluid ounces). The standard US recipe cup.
Cups began as household drinking vessels, not scientific units, which is why they remain the messiest measures in the kitchen. The US customary cup was defined by slicing up the gallon: half a pint, or eight US fluid ounces, about 236.6 milliliters. Unlike the larger units, nobody ever fixed it to a physical vessel, so it exists only as a fraction of the gallon.
The customary cup is not the only American cup. For nutrition labels, US regulation defines a cup as exactly 240 milliliters, a rounder figure that sits slightly above the customary size. Packaged foods therefore list a serving in the legal cup while a measuring cup from the hardware store follows the customary definition. The gap is 3.4 milliliters, which hardly matters for soup but can matter in baking. Cup measures also hide the weight of dry ingredients, since a cup of sifted flour and a cup of packed flour differ substantially, which is why much of the world prefers grams.
1 US cup = 0.2365882365 liters (exactly).

Vedro (vedro)
The Russian 'bucket', about 12.3 L (ten shtofs). The standard Russian liquid measure until metrication.
Vedro means bucket in Russian, and the unit was the main liquid measure of the Russian Empire, used for wine, vodka and other drinks. Wholesale spirits were counted in vedros and in the bochka, a barrel of 40 vedros holding about 492 L.
Peter the Great did not scrap the old Russian units but redefined them against English ones. The liquid vedro was fixed at exactly 750 cubic inches, which gives 12.29941 L, or about 2.7 imperial gallons. A separate dry vedro of 800 cubic inches, about 13.12 L, was used for grain, so the word has two values depending on the goods.
Smaller liquid units were fractions of it: a bottle of vodka was one twentieth, a kruzhka one tenth, a charka one hundredth, and the standard shtof one tenth in the 19th century. Metric units became optional in Russia in 1900, compulsory in the Russian SFSR in 1918, and the Soviet Union dropped the old measures officially in 1925.
1 vedro = 12.29941 liters (approximately).
